Sound and USB/bluetooth issues

Hi - Have I been experiencing more and more issues with the internal speakers not working, USB and bluetooth connection crashing. This got worse since I upgraded to macOS Big Sur.

I ran both hardware and software diagnostic, but nothing has worked so far.

How shall I address this?

You can’t open the “Bluetooth” preferences pane because it is not available to you at this time. I recently updated my 13" 2014 Air to Big Sur 11.6.2 (the latest available for my Mac) and now I'm unable to connect any bluetooth devices or even access the bluetooth settings. I keep getting the message "You can’t open the “Bluetooth” preferences pane because it is not available to you at this time." I have already tried resetting both the SMC and NVRAM following these instructions, but still get the error message https://support.apple.com/en-us/HT201295 https://support.apple.com/en-us/HT204063

Bluetooth stopped working - Big Sur 2020 MBP Having major issues with Bluetooth on my 2020 Macbook Pro/mac OS Big Sur 11.5.2 Was working fine for about a year, then all of a sudden none of my bluetooth devices would connect, or even show up in the bluetooth preferences pane. Devices I've tried to connect: iPad, Topping MX3 headphone amp, Logitech G604, Apple Wireless keyboard. These devices all work fine, and can connect via bluetooth to a windows laptop I have. I have tried all the usual steps of: resetting bluetooth module removing the com.apple.Bluetooth.plist file removing /Library/Audio/Plug-ins/HAL/ resetting NVRAM Any other suggestions I can try?

Bluetooth not working properly after 11.5 upgrade Hello All, I had installed Big Sur on my Late 2016 Macbook Pro 13 and all was working well. I then installed the 11.5 upgrade and after that none of my Bluetooth devices are working properly. The devices connect and are recognized, but they seem to have a connection lag/interference. Audio plays back chopped and both my magic mouse and magic trackpad lag when I move. I tried reseting the bluetooth module, resetting PRAM, and deleting the preferences files. Anybody else having issues? This is very frustrating as mu computer became unusable since I use Bluetooth devices constantly, notable input and audio. Anyway to reverse to a previous version of Mac OS? Thanks anyone for any help.
